However, the high-pressure hydrogen storing tank is greatly barrel-shaped, therefore subtract sometimes for the high-pressure hydrogen storing tank is equipped on vehicle Few car room space, trunk space.That is to say it is possible to which vehicle space can not be effectively utilized.In order to solve this problem, Consider be arranged multiple degree that can be configured in the space of vehicle vacated path tank.However, if setting is multiple Tank, then each tank requires enhancement layer, may in order to ensure the enhancement layer amount space and to car room space, trunk space produce Raw limitation.Therefore, vehicle space is effectively utilized still to leave some room for improvement.
Summary of the invention
The disclosure can obtain the high-pressure bottle that can effectively utilize vehicle space.
The high-pressure bottle of first method includes main part, is formed as cylindric, and it is axial at least side end Opening, the main part be adjacent to radially be equipped with it is multiple；Lid, is formed as axial identical with the axial direction of the main part It is substantially cylindric, and close the opening of multiple main parts；And enhancement layer, be formed as width than the main part Narrow band-like of radial dimension, is set up in the master including the lid using the axial direction of the main part as longitudinal direction Between the end of the side and the end of the other side in the axial direction in body portion, and be set up under end on observation the lid and The position in addition to maximum diameter portion in the main part, the maximum diameter portion are and direction adjacent with main part described in other Position corresponding to orthogonal radial direction.
According to first method, main part is formed as cylindric, and it is axial at least side it is open-ended.Also, Main part be adjacent to radially be equipped with it is multiple.Therefore, pass through the spatial match of the multiple diameters of setting and vehicle vacated Main part, can by vehicle car room space, influence caused by trunk space to be set as minimum limit, and ensure to be contained in master The amount of necessary fluid in body portion.In addition, the opening of main part is closed by lid, and in the axial direction of main part for including lid The end of side and the end of the other side between be provided with enhancement layer.Therefore, can be limited in by the fluid receiving of high pressure in Lid is detached from from main part when the inside of main part.
Here, enhancement layer be formed as width be set to it is narrower than the radial dimension of main part (small) band-like, by main part Axial (hereinafter referred to as " axial direction ") is set up in the end of the side in the axial direction of the main part including lid as longitudinal direction Between portion and the end of the other side.In addition, enhancement layer is set up in the position in addition to maximum diameter portion in lid and main part, this is most Large-diameter portion is position corresponding to the radial direction orthogonal with the adjacent direction with other main parts.That is, can be columned Enhancement layer is set in the space generated in the case that main part is adjacent radially.Therefore, multiple main parts are shown in adjacent row When, the size being able to suppress on the direction orthogonal with adjacent direction is (as an example, radially arranged in the horizontal plane to have master Height dimension in the case where body portion) increase because of enhancement layer, so as to realize densification.
The high-pressure bottle of second method is based on first method, and the enhancement layer is configured to include: the first enhancement layer, described The position in addition to the maximum diameter portion is set up under the end on observation of main part；And second enhancement layer, in the main part The position that is set up under end on observation in addition to the maximum diameter portion and the position different from first enhancement layer, described first plus Strong layer intersects at the lid with second enhancement layer.
According to second method, enhancement layer is configured to include the first enhancement layer and the second enhancement layer.First enhancement layer is in axial direction The position in addition to maximum diameter portion is set up under observation, the second enhancement layer is set up in addition to maximum diameter portion under end on observation Position and the position different from the first enhancement layer.First enhancement layer intersects at lid with the second enhancement layer.That is, being set up in difference Multiple enhancement layers of position are set up in lid, therefore can be improved the retentivity that lid is held in main part.Therefore, it can be improved resistance to Pressure property.
The high-pressure bottle of Third Way is based on first method or second method, is formed with rib on the surface of the lid, institute It states rib and a pair is set opposite to each other in the width direction two sides of the enhancement layer, and along substantially vertical with the face of the enhancement layer Direction it is prominent.
According to Third Way, it is formed with rib on the surface of lid, the rib is set opposite to each other in the width direction two sides of enhancement layer A pair is set, and prominent along the face generally perpendicular direction with enhancement layer.Therefore, enhancement layer is not easy de- from lid by the rib From, therefore the retentivity that lid is held in main part can be further increased.Therefore, it can be improved the resistance to pressure of high-pressure bottle.
The high-pressure bottle of fourth way is based on Third Way, and the winder for winding the enhancement layer is formed in the lid, The winder forms oriented direction protrusion identical with the rib and to a greater degree than the rib position outstanding.
According to fourth way, it is formed with the winder of winding enhancement layer in lid, which forms oriented identical with rib Direction protrusion and to a greater degree than rib position outstanding.Therefore, though for propose large-duty purpose and by enhancement layer It is pre-formed into cricoid situation, by the way that position outstanding assembles the enhancement layer to a greater degree from the rib than winder, adds Strong layer also becomes easy to the assembling of winder and then lid.
